- Banner floats at the very top (over the nav/title area), never pushing the
content below and staying clear of the list/pill.
- Offline banner now fires on refresh in airplane mode / no data: the mirror
live chain bypassed the HTTP cache (+10s timeout) so an offline fetch really
fails instead of silently re-serving a cached pointer+dump as a 'success'
(which kept dataStatus .live and hid the banner).
- Onboarding permissions fire at the Continue/Allow tap BEFORE advancing, so
the system prompt appears after the page is read and never covers the next
page's animation (grant auto-advances).
Legend rows now show each station's average over the days shown
in brackets (pence; signed +X.Xp in vs-cheapest mode, matching the
list-row deltas). Footer under the key explains the figure per mode.
averagePence helper (nil for empty series) + 3 tests; -showTrends
becomes a permanent QA hook like -showKeySheet.
- Shared/FuelHistory.swift: GitHub mirror read path (latest.json pointer +
history/YYYY-MM-DD.json day files); day math (UTC noon keys), slim day decode
with the shared price band, series + deltaSeries (vs-cheapest rebase),
favourites-only app-group cache (90-day prune), parallel per-day fetches,
404/network = graph gap never error.
- FuelPriceProvider: shared priceBand + mapGrades (single source for live +
history decoding).
- FuelBoard/TrendsView.swift: line chart in the Favourites tab via toolbar
button + sheet; fuel capsule (fuels with favourites only), 7/30/90 range,
Price/vs-cheapest toggle, per-station legend, price-display style on y-axis,
empty/loading/retry states with honest copy; no widget in v1.
- Localizable.strings: Trends keys.
- 83 tests (13 history + URL regression): day math, band guard, series gaps,
delta rebasing, prune, and the appendingPathComponent regression (relative
URL resolution dropped /main — all fetches 404'd).
- Sim-verified: favourites rows + TOP/deltas; sheet controls + building-up
state with live first-snapshot date (archive has 1 day; lines render once
>=2 snapshots).
- Backlog: P1 Trends DONE (unmerged); P0 REMAINING = live provider chain +
telemetry beacon.
